ply above 100% rated output. Limit your programming voltage to 10 Vdc.

Remote Programming Connections. Remote programming requires changing settings of the switch and connecting external voltages to + and - terminals of "CV" or "CC" on the rear panel. Any noise picked up on the programming leads will appear on the supply's output and may degrade regulation. To reduce noise pick-up, use a twisted or shielded pair of wires for programming, with the shield grounded at one end only. Do not use the shield as a conductor.

Notice that it is possible to operate a power supply simulta- neously in the remote sensing and the remote analog program- ming modes.

Remote Programming, Constant Voltage. Figure 6 shows the rear panel switch settings and terminal connections for remote- voltage control of output voltage. A 1 Vdc change in the remote programming voltage produces a change in output voltage (volt- age gain) as follows: E3614A: 0.8 Vdc, E3615A: 2 Vdc, E3616A: 3.5 Vdc, E3617A: 6 Vdc

MULTIPLE-SUPPLY OPERATION

Normal parallel and auto-parallel operation provides increased out- put current while normal series and auto-series provides increased output voltage. Auto-tracking provides single control of output volt- age of more than one supply. You can set up the unit for multiple- supply operation by changing the settings of the rear panel switch and connecting the leads from the rear panel terminals to the load. Solid conductors of 0.75 to 1.5 mm2 can be connected to the rear panel terminals by simply push fitting. Thinner wires or conductors are inserted into the connection space after depressing the orange opening lever.

NORMAL PARALLEL OPERATION

Two or more power supplies being capable of CV/CC automatic cross over operation can be connected in parallel to obtain a total output current greater than that available from one power supply. The total output current is the sum of the output currents of the individual power supplies. The output of each power supply can be set separately. The output voltage controls of one power sup- ply should be set to the desired output voltage; the other power supply should be set for a slightly higher output voltage. The sup- ply with the higher output voltage setting will deliver its constant current output, and drop its output voltage until it equals the out- put of the other supply, and the other supply will remain in con- stant voltage operation and only deliver that fraction of its rated output current which is necessary to fulfill the total load demand. Figure 8 shows the rear panel switch settings and terminal con- nections for normal parallel operation of two supplies.

AUTO-PARALLEL OPERATION

Auto-parallel operation permits equal current sharing under all load conditions, and allows complete control of output current from one master supply. The control unit is called the master; the controlled units are called slaves. Normally, only supplies having the same model number should be connected for auto-parallel operation, since the supplies must have the same voltage drop across the cur- rent monitoring resistor at full current rating. The output current of each slave is approximately equal to the master's. Figure 9 and Fig- ure 10 show the rear panel switch settings and terminal connections for auto-parallel operation of two supplies and three supplies.
